The Qdrant points are returned in clustered groups.\n* Each group is looped to fetch the payloads of the points and feed them to the AI agent to summarise and generate insights for.\n* The resulting insights and raw responses are then saved to the Google Spreadsheet for further analysis by the researcher or the HN user.\n\n### Requirements\n* Works best with lots of comments!\n* Qdrant Vectorstore for storing embeddings.\n* OpenAI account for embeddings and LLM.\n\n### Customising the Template\n* Adjust clustering parameters which make sense for your data.\n* Adjust sentimentality setting if comments are overwhelmingly negative at times.", "workflow": { "meta": { "instanceId": "408f9fb9940c3cb18ffdef0e0150fe342d6e655c3a9fac21f0f644e8bedabcd9" }, "nodes": [ { "id":
